But here's a guy who says he's okay with it: Alex Kazim, founder and CEO of news aggregation platform Ongo, who also used to work at Skype, eBay, PayPal, and very long ago, was a software developer at Apple.

Kazim says he thinks the vast majority of his company's new subscribers will come in through the web, where he wouldn't have to pay a 30% bounty to Apple -- as opposed to signing up through his iPad app, where he would have to pay Apple. (Ongo aggregates a bunch of news sources into a single website, with no ads, and wants people to pay $7 per month for it.)

As long as it's still a relatively small percentage of his customer base that he has to pay a 30% acquisition cost for -- and if Apple is using the money to help market your app, and bring in new users -- he says he's fine with it.
